Is there a better sequel than Terminator 2?

I qualify a good sequel as a movie that can be enjoyed without having to watch the previous. Not that the previous isn't important, just not required.

Terminator 2 clearly fits into this category. As do a lot of sequels. Here is my short list:

• Terminator 2
• The Dark Knight
• Finding Dory
• Toy Story 2
• Spider Man 2 (Toby Maguire)

Do Casino Royal or Rogue One count for anyone?
